ADDING MACHINE.

Application led December 24, 1925. Serial No. 77,545.

This invention is directed to an improvement in adding machines, constructed primarily with a View t0 permitting all necessary and desirable operations incident to such machines, while at the same time materially reducing the number of parts and simplifying the cooperation of such parts to reduce the cost of manufacture.

The present invention has for its object the provision of an adding machine, in which, through the use of the usual key levers, the number to be added may be set up on the number wheels and added to the totalizing wheels, with simple provisions for carrying over from one wheel to the next higher rdigit wheels. A simplified construction is provided whereby at will the numbers set up on the number wheels or on the totalizing wheel may be readily printed; the construction providing a resetting mechanism to restore the wheels to normal or starting position.

The invention is illustrated in the accompanying drawings, in which:

The improved adding machine comprises a readily portable structure, including a base 1, and a casing cover 2, removably setured to the base and appropriately formed to house the mechanism7 the upper wall of the casing cover having a convex section 3, formed with a series of longitudinally ranging parallel slots 4 for the manual ad- ]ustinent of theV key levers. The casing wall adjacent the slots is marked with appropriate numbers to indicate the proper position of the key levers in setting up particular numbers. l

A shaft 5 is mounted in the side walls of the casing and rotatively supports a series of independently mounted key levers 6, adapted to project through the respective slots 4. and each provided beyond the casing with a handle portion 7. If desired, and as preferred, one wall of each of the slots 4 may be formed with indentatione 8, aligning with the particular numerals adjacent such slot7 and the corresponding key lever provided with a spring pressed element 9 adapted to engage in said indentations to more or less accurately position the lever and at the same time prevent casual displacement thereof.

Integral with the hub of each lever 6 is a number wheel operating segment 10 having operating teeth 11, arranged concentric to the axis of the key lever and adapted to cooperate with the number wheels for setting up the numbers in accordance with the movement of the key levers. These segments 10 'will be hereinafter termed the number segments. An additional or totalizing segment- 12 is also mounted on and movable with the hub of each key lever. these totalizing segments having peripheral coneentrically arranged teeth 13 for cooperation with the totalizing wheels. The totalizing segments are mounted for a limited relative movement with respect to the hubs of the particular key levers.y in order to permit the carrying` over from one totalizing Wheel to the next While a segment is engaged there- With. The particular construction tor this purpose Will be later explained.

A number Wheel sha'tt 1a is mounted at its ends in the side Walls ot the casing cover in a manner to permit a sliding movement ot the shaft longitudinally of the casing, and on this shaift are mounted number discs 15, having' appropriate peripheral numbers from zero to nine also blanks. Adjacent each number disc or Wheel, and secured to or forming a iixed part thereof, is a pinion 16 having peripheral teeth 17 to be engaged by the teeth 11 ot the particular key lever number segment 10, thus permitting the particular number Wheel to be set up With the desired number through the operation ot the corresponding key lever to that number indicated on the casing cover. A totalizing Wheel shatt- 18 is mounted beloW the number Wheel shaft- 14. The `ends of this shatt are slidably supported in slotted bearings 19 in the lWalls of the casing, and on the shalt are a series of totali/:ing discs 20 having appropriate peripheral numbers trom zero to nine and each havine' a relatively iiXed pinion 21 arranged in the path of movement ot the particular totalizing segment 12 on the corresponding key lever. It is to be noted from Fig. 1 in the draWings that While the number ysegments 10 are normally in engagement With the pinions ol the number Wheels7 the totalizing segments 12 are normally out ot engagement With the pinions ot' the totalizing Wheels. Thus in normal position, the totalizing Wheels are free of engagement With the totalizing segments. so that in the operation ot any one of such segments, through movement oit the key lever` a carrying over betWeen the totalizing Wheels is readily permitted Without interiorence from the'totalizing segments.

An important detail ot the present invention resides in the means Whereby 'the number Wheels and totali/zing Wheels may from time to time as desired be moved to printing position for' indicating kthe sucessive numbers set up on 'the number Wheels and the total ot any desired series oit such numbers. F or the purpose of receiving the impressions from the respective sets ot' Wheels, l provide the usual paper tape 22 from a reel supply 223 supported beyond the casing, 'the tape being led over guide rollers 24 and over an intermediate platen 25 on the inner side et the rear Wall of the easing cover. The usual inked ribbons 2G and QT from spools QS are fed by any appropriate mechanism over the surlace ot the paper tape in the printing line of the ninnber Wheels and totalizing Wheels. For the printing movement ot the number' Wheels. it Will be seen that the shaft lil is mounted adjacent its respective ends in bearing 29 carried by longitudinally ranging bars 30, supported in guides 31 fixed to the casing. At their ends remote from the number Wheels, that is, at the trout end ot the casing, the bars SO bear against discs 32 eceentrically mounted on a shaft 33 supported at its ends in the casing, and provided at an appropriate point With a pinion Se to be engaged by a segment 235 mounted upon a sha'lt $36 supported in the casing and provided beyond the saine With a handle 3.7 Which may be termed the number printing handle.

is Will later appear, the actuation ot' the number printing handle operates automatically to restore all ot' the set or operated key levers to normal or inoperative positions, and under these conditions it is ot' course necessary that during this resetting ot' the .key levers, the totalizing Wheels be out oit' engagement- With the totalizing segments ot the operated key levers. Other- Wise, this resetting of the key levers Would reset the totalizing Wheels or it' such could not be moved rearward, Would tend to a breakage of the parts. The VfolloWing provision is therefore made to move the totalizing Wheels beyond the possible influence of the totalling segment, `Without permitting a printing movement of such totalizing Wheels, under the operation of the `number printing handle 37.

To secure this desired movement oi the totalizing Wheels as a unit, a shaft 38 is mounted in the casing beloW the shaft 323, on Which shaft 3S is provided a disc 39 to W rich is connected a link 40, in turn secured to totalizing Wheel operating bars L11, to be later oescribed. A toothed segment 42 is secured upon the shaft 238, and is engaged by a Vpinion 43 on the shaft 36, The pro portions ot the segment 35 and pinion 34 are such that in the I nedetermined movement ot' the handle 37, the bars 30, and therefore the number Wheels, Will be `moved to printing position, that is, to impress the numbers set up on said Wheels through the inked ribbons 26 onto the paper tape 22 and back again to normal position. The relative proportions of the segment 212 and pinion i3 hoWever, are such that in the movement of this handle. the bars 41 Will be moved a materially less distance than the bars 30, so 'that as the number Wheels are moved to printing position and back again, the totalizing Wheels Will be `moved toWard but not to printing position, thus arranging the totalizing Wheels beyond the intlnence oil: the totalizing segments. Springs connected to the easing and to tbe bars 30, tend to return the number Wheels to normal position in the return movement of the handle 37, the totalizing Wheels being in this movement ot the handle draWn to normal position.

lll() lt is of course necessary to provide for a printing operation of the totalizing wheels in order that the final product of any series of operations of the machine may be had,

and this of course necessitates providing for two independent movements of the totali?.- ing wheels as a unit, one incident to their partial movement during printing' movement of the number wheels, and another incident to their full printing movement. f

To provide for the printing opera-tion of the totalizing wheel unit, a shaft is mounted transverse the casing below the bar 41, and an operating handle 46, hereinafter termed the totalizer printing handle, is connected to one end of the shaft beyond the casing. Secured to the shaft within the casing is an arm 47, connected to a bar 48, slidably mounted in the guides 31, and bearing at its forward end against the shaft 18. Of course the Varm 47 and bar 4S is duplicated at the opposite side of the casing, and it is obvious that upon operation of the totalizer printing handle l-G, the totalizer wheel unit may be advanced to print the numbers set. up thereon on the paper. 0f course it will be reineniberefil that this totalizer wheel unit is aftuated partly towards printing position by bars il, and to permit the unit to move to printing position without operating the bars all, the latter, as indicated in Fig'. 1.4, are terminally formed with an open box-like end 49, through which the shaft 18 passes, and in which the shaft is held at one end of the box 49 by a spring 50 bearing against a follower 5l formed to partly embrace the shaft. By this construction, the totalir/er wheel unit may be moved a portion of the distance toward printing position, as when operating the number wheel printing han-- dle, or be inovedthe full distance to printing position as when operating the totalizer printing handle 46.

In connection with the operation of the number wheels to printing position, provision is made for automatically restoring all of the operated key levers to normal or starting positions, the resetting movement being accomplished as the number wheel printing handle 37 is being retracted from printing position. The resetting mechanism includes a bar 52 supported in advance of the key levers by arms 53 freely rotatable on shaft Each of the arms is provided with a forwardly extending rod terminating in a rectangular yoke hav- I ing a projection 5G extending downwardlv from its upper wall. An arm 57 extends from shaft 36 and has a lateral piu 58 to normally play in the yoke 55 and to ei'igapge the projection 56 when in appropriate position. yThe cam tracks 59 having upper in` clined surfaces are arranged in position to be engaged by the forward ends of the yokes 55 to bodily elevate the yokes as such yokes reach a predetermined position in operation. y

ln the key resetting mechanism, it will be apparent that in the operation of the first key lever, the bar 52 will be moved forwardly, thus freeing all the key levers and causing the bar to follow forward that key lever which may be operated the limit in that direction. As the bar 5i. is moved, the yokes 55 are correspondingly moved forward, as indicated in dotted lines in Fig. l0. On movement of the number wheel printing handle to the left to move the number wheels to printing position, the pin 5S on the arin 5i", will ride lengthwise the yoke and .finally in rear of the projection 56.r is the printing handle is returned to normal position, the pin 58, through engage 'ient with the projec Von 56, will force the bar forwardly and thus ire to normal position all operated key levers. As the movement con. ies, the yoke will ei'igage the cam track .ii-Sl and be gadually raised until when Vthe parts have rea,l d their normal positions., the progection 56 will be raised out of the path of the pin 58, and no further niovement'of the bar will be caused, though it unde od at this time the n" i have not been fully rroer wheeis returned to normal position.

lt will of course be apparent that as the key levers are returned to normal position, the number segments and totalizing segments will be coirespoiidiiiglv returned to normal position, and rif du this operation the totalizing 'ient-s nave been in i'i'iesli with the pinions of the totalizing wheels, the movements of the wheels would have been reversed exactly to the saine ei:- toit. that they had previousr,y been set up. lt for thf son that in the printing movement of the number whe'r s the totalizingr wheel unit is nioved l .ward wholly free of influence of the to so that in the rescuing of the key levers, the totalifiinq` whe are not effected.

It may frequeiitly happen that while a totalizing' .segment i, in cooperation with the pinion of a part lolar to lining wheel through the operaton of a l-Ley lever, that such tilitalizing wheel will be advanced through the carry over meel 'im from the operation of the pre-f,l these circunif-t must be cap;

inging segment,l U0

the particular recesses 91 of the totalizing wheels. `In a l'ull travel of the bar 87, all the totalizing wheels will be picked up and turned t0 a position so that all of their recesses 91 will be in alignment'transversely oit the casing immediately beneath the oll'set 93 ot' the guide 91. At this point, the bar 87 will be pressed into the ofset, freeing the totalizing Wheel. lt is of course miden stood ,that when the recesses 91 of the totalizing- Wheels are in this position, the zero figures on each oit said Wheels will be in printing line, that is, the totaliaing Wheels will be in normal positions.

It will be noted that the construction as a whole provides an 'adding machine in which the usual tabulating or number Wheels may be set up through the operation of the key levers, such levers serving at the same time to up the totalizing wheels, the number Wheels or totalizing Wheels being l "'r printing at will, With all oper at ,t key leers automatically restored to normal position during the movement of the number Wheels from printing to operative positions; the automatic locking of the key levers against 4casual displacement during the printing operation ot the number `wheels; and the clearing up of the totalizing wheels, with the mechanisms leading to the `carrying out of these operations of a simple compact nature involving the use and requirements of but few parts, whereby the machine as a whole, While capable ot' pertorming all the functions of the usual addingv machine, is materially simpliiied to insure more certainty of operation and material less cost in n'ianufacture.

Yft is lobe noted that there is provided in shait 33, a clutch 94 through which the handle. 37V isv permitted to be returned to normal positon Without operating the parts, the clutch slipping in this movement and through Vwhich the handle 46 may be operated without similarly actuating the handle 37.
